Add Rust scope-resolution integration tests (RFC #909 Ring 3)
Tests cover the core deliverables for the Rust scope-resolution pipeline:
- impl blocks and trait implementations
- Module resolution (crate::, super::, self::)
- Struct fields and type bindings
- Self/&self/&mut self receiver binding
- Generic functions (V1 ignores generic args)
- Grouped imports (use foo::{A, B})
- Renamed imports (use foo::Bar as Baz)
- Arity checking (no overloading)
- Struct literal constructor inference
- Return type inference
- Scoped/qualified calls (Foo::new())
- Enum declarations
- Multiple impl blocks
- Free function calls
- Typed let bindings
